Percolation‐Driven β‐Relaxation Enables Resonant Acceleration of Crystallization in Amorphous Phase‐Change Materials

Advanced Materials, EarlyView.
Mobile‐atom percolation underlying β‐relaxations fundamentally dictates the crystallization pathways of phase‐change materials. High‐frequency ultrasonic excitation dynamically modulates this critical mobility percolation network, substantially accelerating the crystallization process.

Textile‐Based Capacitive Pressure Sensors Enabled by Ultrasonic Spray‐Coated Carbon Black Electrodes and Electrostatic Flocking

Advanced Materials Interfaces, EarlyView.
A 4‐layer Kevlar‐based composite is fabricated by combining ultrasonic spraying and electrostatic flocking. Carbon black dispersion is first deposited onto Kevlar fabric to create a conductive electrode. Nylon fibers are then electrostatically flocked onto the coated fabric, forming a dielectric layer.

Photothermal Heat Spreading for Uniform Pixel Activation in NIR Laser‐Driven Thermochromic Liquid Crystal Displays

Advanced Materials Interfaces, EarlyView.
A pixelated full‐color display is driven by a 1064 nm near‐infrared laser without electrical wiring. A graphite photothermal layer converts light into heat, while an aluminum heat‐spreading layer redistributes it for uniform color within each pixel. Optimizing pixel size and spacing suppresses thermal crosstalk, enabling non‐contact reproduction of ...
